ABSTRACT:
Power supply apparatus according to the present invention may comprise a direct current source and a phase-shift converter circuit connected to the direct current source. A rectifier is connected to the output of the phase-shift converter circuit and rectifies a modulated output signal produced by the phase-shift converter circuit. An average current sensor connected to the rectifier senses the time average current in the rectifier and produces an average current feedback signal. A control device connected to the average current sensor and to the phase-shift converter circuit is responsive to the average current feedback signal and operates the phase-shift converter circuit in accordance with the average current feedback signal.
